What is in “magic mushrooms” that makes them work?
The primary active ingredients of Psilocybe mushrooms are psilocybin and psilocin, and to a lesser extent baeocystin and norbaeocystin. The ratio of psilocybin to psilocin varies from species to species. The primary difference is that psilocin is unstable and it breaks down when the mushroom is dried, while psilocybin lasts much longer (a 115-year old mushroom sample was found to contain some). The two are equally psychoactive, since one molecule of psilocybin breaks down into one molecule of psilocin.
